IPAIPER CONTAINER.

Specification of Letters Patent.

Patented July 141-, rats.

To all whom it may concern:

lie it known that I, WILLIAM L. PoFrEN- mum-2n, a citizen of the United States, and residentof St. Louis, Missouri, have invented certain new and useful Improvements in Paper Containers, of which the following is a specification.

My invention relates to improvements in paper containers which has for its object to provide a container constructed of paper, substantially conoidal in form, and whose closure is effected by flattening the mouth of the container.

In the drawingsFigure 1 is a front elevation of a container embodying my invention, showing a portion broken away. Fig. 2 is a rear elevation of the same, showing the lower portion in transverse section. Fig. 3 is a side elevation of the upper portion of the container. Fig. 4 is a: transverse vertical view in section of the upper portion of the container.

As shown in the drawings, the main body of the container of my invention is conoidal in form and is constructed of a single sheet of paper, indicated by the numeral 5, the vertital meeting edges of which are overlapped and secured together by means of vertical parallel rows of stitching t3 and 7. At the lower and larger mouth of the body section thus formed, I employ a bottom of the form shown in section in Fig. 2, hav* ing the depending circular flange 9 which secured to the body mcmbcr by means of the parallel horizontal rows of stitching l0 and 11. Between the vertical rows of stitching 6 and 7 a metalli stiffening member 12 is inserted, its upper end extending to the plane of the upper mouth of the body section. The container thus formed, prior to its filling, is of the fprm illustrated in Fig. 1. it hen the contents has been placed within the container, the mouth of the body section is closed by being flattened, and the mouth is then bent. over upon itself in the manner illustrated in Figs. 2, 3 and 4; the metallic stiffening member 12 serving to hold the mouth closed. The rigidity of the metallic member 12 sufiiccs to keep the mouth of the container closed for ordinary purposes of trade.

Where it is desired, however, to seal the closure to prevent the intentional removal of the contents, I provide the sealing device illustrated in Fig. 2; perforations l3 and 141 being made through the upper end of the container, and the cord 15 being inserted through the perforations 13 and 14: and its free ends sealed by means of the me tallic seal 16. Such form of scaling is peculiarly adapted to use of the container as a receptacle for milk or other food prod ucts, where it is desiredto give the ultimate consumer the assurance that the contents have not been tampered with during their transmission from the producer to the consumer.

Where the container is used in distributmg products only in bulk by the dealers and sold direct to the ultimate consumer, the closure indicated in Fig. 2 by the numeral 17 will be made by flattening the walls of the body section upon itself and folding over the flattened portion thus formed at any desired point which will leave the closure at a plane above the level of the contents of the container; thus, the con tainer having a capacity of one pint is employed in the sale of a one-half pint of merchandise; the closures 17 will be at a point proportionately lower than the pointillustrated in Fig. 2, to sufiice to leave comparatively little air space above the level of the contents.

' Having fully described my invention, what I claim as new and desire to have secured to me bythe grant of Letters Patent, is:

1. As a new article of manufacture, a paper bottle whose side walls are formed of a single blank cut to form a truncated cone, the meeting edges of said blank being overlapped and stitched together, said bottle havinga circular bottom member fitted in the larger end of the bottle and provided with a downturned annular marginal flange which is secured to said side walls by stitching, the bottle so constructed being treated to make the paper impervious to moisture and the seams watertight.

2. As a new article of manufacture, a 100 paper bottle whose side walls are formed of a single blank cut to form a truncated cone, the meeting edges of said blank being stitched together, said bottle having a circular bottom provided with a downturned 105 circumferential flange which is secured by I stitching to the side walls of the bottle, the bottle so constructed being treated to make the paper impervious to moisture and the 'scams watertight, the open end portion of the bottle being adapted to be folded to seal the bottle.

In a paper container, the combination of a conoidal body formed from a single sheet of paper whose meeting edges are secured by two or more parallel and Vertical lines of stitching; a bottom member secured in place at the lower end of the body memher by means of one or more lines of stitch a ing; the mouth of the body member being folded over upon itself to form a flat closure and sealing devices extending through said closure, substantially as descrlbed.

4. In a paperwontainer,the combination of a conoidal body formed from a single sheet of paper whose meeting edges are s ecured in place by two or more parallel and vertical lines of stitching; a flanged bottom member secured in place at the lower mouth of the body member by means of one or more lines of stitching passing through the flange and the body member; a metallic stiffening member mounted between the meeting edges of the body member and between two of said parallel and vertical lines of stitchin and adapted-to be bent over uponitself when the mouth member is flattened, to form a closure, substantially as described.

5. As a new article of manufacture, a truncated conical bottle constructed of waterproofed paper, whose side Walls are formed of a single blank cut to form a truncated cone, the meeting edges of said blank being secured water tight together by non-adhesive means, said bottle having a closed bottom in its flaring end, and the open =end portion of the bottle being adapted to be collapsed and folded to form a closure.

In testimony whereof, I have signed my name to this specification, in presence oftwo subscribing witnesses. v
